<p>Earlier versions of the Linux kernel added a NULL byte to the end of the
SSID to enable easy printing of the SSID on the console or in a terminal,
but this behavior was problematic (SSIDs are simply byte arrays, not strings)
and thus was changed. This function compensates for that behavior at the
cost of some compatibility with odd SSIDs that may legitimately have trailing
NULLs, even though that is functionally pointless.</p>

<p>Wi-Fi SSIDs are byte arrays, they are _not_ strings. Thus, an SSID may
contain embedded NULLs and other unprintable characters. Often it is
useful to print the SSID out for debugging purposes, but that should be the
_only_ use of this function. Do not use this function for any persistent
storage of the SSID, since the printable SSID returned from this function
cannot be converted back into the real SSID of the access point.</p>
<p>This function does almost everything humanly possible to convert the input
into a printable UTF-8 string, using roughly the following procedure:</p>
<p>1) if the input data is already UTF-8 safe, no conversion is performed
2) attempts to get the current system language from the LANG environment
variable, and depending on the language, uses a table of alternative
encodings to try. For example, if LANG=hu_HU, the table may first try
the ISO-8859-2 encoding, and if that fails, try the Windows-1250 encoding.
If all fallback encodings fail, replaces non-UTF-8 characters with '?'.
3) If the system language was unable to be determined, falls back to the
ISO-8859-1 encoding, then to the Windows-1251 encoding.
4) If step 3 fails, replaces non-UTF-8 characters with '?'.</p>
<p>Again, this function should be used for debugging and display purposes
_only_.</p>
